Fig. 4From: CT perfusion for response evaluation after interventional ablation of hepatocellular carcinoma: a prospective study71-year-old male patient with liver cirrhosis and right hepatic lobe segment VIII HCC underwent TACE on June 2019. Follow-up post-intervention triphasic CT was done on August 2019 and revealed dense injected chemotherapy material “lipidol” showing evidence of pathological enhancement at its lower margin, denoting recurrent/residual activity. CTP functional maps of this recurrent lesional pathological activity showed evident increase in blood flow measuring about 239 mL/100 g/min compared to 96 mL/100 g/min in the non-ablated hepatic parenchyma. In addition, the mean transit time is reduced to become 8 sBack to article page
